QLE7340 Host Channel Adapter

High Performance Computing (HPC) solutions have used InfiniBand (IB) networks to meet the needs of the most demanding set of applications and grand challenges. The QLogic QLE7340 is a single-port 40Gbps InfiniBand PCI Express� Gen2 x8 Host Channel Adapter (HCA). It is a highly integrated design that delivers unprecedented levels of performance, making it the ideal solution for HPC applications that rely on low latency, direct memory access.

Data Center and Enterprise

The supporting software includes standardsbased high performance sockets, a Linux TCP/IP stack, an OpenFabrics (OFED) stack, and QLogic�s value added Upper Layer Protocols (ULPs) over OFED. For data center applications, the QLE7340 supports storage and networking. With three different stacks available, the high performance sockets and the Linux TCP/IP stack can be used simultaneously with the OFED stack. QLogic also provides management features such as IFS tools and subnet management.


InfiniBand ecosystem partner certifications, combined with agency and regulatory testing, ensures all products meet industry compliance with hardware and software specifications. All HCAs are tested extensively with third-party hardware, along with multiple software applications, to ensure best-in-class InfiniBand interoperability and compatibility.

Investment Protection

For over 15 years, QLogic has been a technological leader with products that address the current needs of customers, yet provide strong investment protection to support emerging technologies and standards. QLogic stands alone in the industry with its product portfolio depth and experience in successfully delivering technological solutions that address the needs of today and tomorrow.

Environmentally Friendly

The only QDR capable adapter available that is RoHS 6 compliant, Antimony- and Halogen-free, and consumes less than 4W (single-port) of power.
